Hello. This would be my first boss.
I got the script from this site:
https://github.com/VSH2-Devs/Vs-Saxt...lugin-Tutorial )
I hope you will like it.
The .smx file should be placed in the tf/addons/sourcemod/plugins folder.
The .sp file should be placed in the tf/addons/sourcemod/scripting directory.
The config should be placed in tf/addons/saxton_hale/boss_cfg.
Everything worked for me during testing. I hope it works out for you too.
